The X-Ray – Bilateral Mastoid OBL is a diagnostic imaging procedure used to examine the mastoid bones located behind both ears. This test uses oblique (angled) views to provide a clearer and more detailed visualization of the mastoid air cells and surrounding structures.

Imaging both sides allows for comparison between the right and left mastoid regions, helping to identify asymmetry, infections, or abnormalities. The oblique view is particularly useful for evaluating the internal structure of the mastoid bone, which may not be fully visible in standard views.

This test is commonly used to detect conditions such as mastoiditis, chronic ear infections, bone erosion, or other structural abnormalities. It is quick, non-invasive, and plays an important role in diagnosing ear-related conditions and guiding further treatment.

The purpose of the X-Ray Bilateral Mastoid OBL is to evaluate the structure and condition of both mastoid bones.

It helps to:

• Detect infections such as mastoiditis
• Assess mastoid air cells and bone structure
• Identify bone erosion or abnormalities
• Compare both sides for asymmetry
• Evaluate complications of chronic ear infections
• Support diagnosis of ear-related conditions
